I believe (no proof) that the Heat 2 Pearl had HoloFlex in it like the Cuda 2000 and the Reaction Ricochet did. The combo of HoloFlex and Mica (the pearlization componnent) may have been what prevented the Heat 2 Pearl from being able to be re-surfaced properly. This is only a guess. Sveral of use here have had exactly the same experience with the H2P. there is at least one person here who also has had his H2P last 500 games or more. Several local people and a few ballreviews people have also had good experience with their Cuda 2000s lasting a long time also. I suspect they may have only polished their balls and never taken sandpaper to them. Sandpaper may be what destroyed the Holoflex. This is all just a guess because Columbia/Track technicians have never commented on this material, HoloFlex, but they have also never but it in another ball, as far as I know.
Oddly, my Heat 2 solid, which is also supposed to have Track's Holoflex equivalent, called "Pegaxis Pro", has been sanded, polished, sanded and polished and has reacted very well to all surface changes with no loss in hitting power. This coverstock, Pegaxis Pro, was also never again used in any Track ball.
